How do we get the ECU code 128 removed on a 2003 Sterling Acterra Truck?
We have replaced the sensors of high colant temperature and coolant level temperature and it is still on and a buzzer stays on with the gas pressed. The buzzer doesn’t come on until the gas is pressed down.

ECU problems codes are diagnostic outputs from the ECU, used to indicate in what area a problem lies. Usually the check engine warning light (on the dash) will come on for a serious problem, but will not necessarily come on for a minor problem. The ECU will remember problem codes with the ignition off; the only way to clear the codes is to disconnect the battery or remove the hazard fuse for half a minute or so.
Hope this helps.

Semi tractors are a little different than cars.
You need to have the computer reset with a diagnostic machine at a dealer, or truck shop.
ADDED:
You may try this:
Turn the key on, but don’t start the truck.
Press the throttle to the floor three times.
Turn the key off.
Wait 30 seconds.
Start the truck and let it idle for a minute or so.
No guaranties, but it’s worth a try.
I know that works on GMC commercial trucks.
